CA 2570691

The invention relates to a method for transmitting a predetermined pulse sequence (I1, I2, I3) on a power distribution network (3) transmitting a determined voltage (Uac), wherein the pulses are embodied in the form of high-frequency interfering pulses naturally transmitted by an electric element (1) which is connected to the distribution network by a switch (2) controllable by a control signal (CS) in such a way that said high-frequency interfering pulses are transmitted at the control signal rate. In one embodiment, the control signal is used as a data carrier in such a way that the data carrying high-frequency interfering pulses are transmitted at the control signal rate.

L'invention concerne un procédé pour émettre une suite prédéterminée d'impulsions (I1, I2, I3) sur un réseau (3) de distribution d'électricité véhiculant une tension déterminée (Uac), dans lequel les impulsions sont des impulsions parasites haute fréquence émises naturellement par un élément électrique (1) qui est relié au réseau de distribution par un moyen interrupteur (2), le moyen interrupteur étant piloté par un signal de contrôle (CS), de sorte que les impulsions parasites haute fréquence sont émises au rythme du signal de contrôle. Selon un mode de réalisation, le signal de contrôle est porteur de données, de sorte que des impulsions parasites haute fréquence porteuses de données sont émises au rythme du signal de contrôle.
